Description

Steel spring rubber snubber
[technical field]
The utility model relates to a kind of vibration damper, especially relates to a kind of vibration damper that is used for various pipelines and machinery suspension vibration isolation, belongs to the environmental protection machinery field.
[background technique]
In building, chemical industry, oil, iron and steel, medicine, food, papermaking, in the industries such as air-conditioning, a lot of machinery or pipeline need hang installation, for example all kinds of air-conditioning ducts, chemical pipeline, blower fan, wind cabinet etc., the situation of the influence of vibration surrounding environment that produces because of machinery or external influence of vibration machinery and pipeline is quite a few, no matter be environment around the influence of vibration that produces of machinery or external influence of vibration machinery and pipeline, these vibrations all are the vibrations that is harmful to, need be eliminated or be excluded, normally adopted rubber pad vibration damping equipment or suspension type steel spring vibration damping equipment.Though the rubber pad vibration damping equipment has the effect of vibration damping, damping constant is big, and the effect of vibration damping and vibration isolation is not clearly; Though the damping property of steel spring vibration damping equipment is better than rubber pad vibration damping equipment, steel spring has the weakness that amplitude increases sharply when producing resonance phenomenon and resonance, has shortcoming and defect.
[innovation and creation content]
The purpose of this utility model is, the advantage that keeps above-mentioned rubber pad vibration damping equipment and suspension type, steel spring vibration damping equipment overcomes and eliminates above-mentioned shortcoming, provides a kind of vibration damping and vibration isolation performance good, can not produce resonance phenomenon again, the steel spring rubber snubber that amplitude increases sharply in the time of eliminating resonance.
The utility model is realized by adopting following technological scheme for achieving the above object: adopt good characteristics and the big advantage of rubber damping coefficient of helical steel springs damping property, constitute a kind of helical steel springs rubber snubber of new structure.
Described helical steel springs rubber snubber is by helical steel springs and be wrapped in the rubber sleeve of its outer ring and be arranged on two rubber columns of helical steel springs upper and lower end; Pass the pull-rod device of two rubber columns and helical steel springs; Fixing bolt and tubular shell constitute.
Rubber sleeve is wrapped in the outer ring of helical steel springs, two rubber columns place the upper and lower end of helical steel springs respectively, and by center platen and press table isolation, the suspension pull bar passes the bottom of top board, upper end rubber column, center platen, helical steel springs, press table, lower end rubber column and tubular shell and stretches out, and fixing bolt then passes the cover plate at tubular shell top and stretches out.
Helical steel springs has high elasticity, characteristics that natural frequency is low, but amplitude increases sharply when being easy to generate resonance phenomenon and resonance, and rubber is except that having certain absorbing vibration-damping function, its damping constant is big, can eliminate helical steel springs resonance phenomenon and when resonance the amplitude shortcoming of increasing sharply, the two organically combines, then complement each other, has two-fold advantage, quite significantly vibration damping and vibration isolation effect is arranged in the interfering frequency scope of broad, equifrequency is functional, and when equipment during greater than load rating, the natural frequency of the utility model vibration damper can remain unchanged; It is strong that resonance peak is suppressed ability, be particularly suitable for hanging the low frequency solid-borne sound transmission that isolation causes because of vibration equipment, as the height line ball of the power transformer of entering the room row's support hangs vibration isolation, the pipeline of air-conditioning water pump, indoor frequency conversion living pump, support hang, the vibration isolation suspensions of indoor low speed blower fan, wind cabinet etc. have tangible vibration damping and vibration isolation noise reduction to solid-borne sound transmission.Its superior performance, simple in structure, reasonable in design, easy for installation.
